Question

Hello can you assist me please i need to solo e and Identity sine cosine or tangent and identify opposite hypnose or adjeact.Number 11.

Answer 1

Given the Right Triangle shown in the exercise, you need to use the following Trigonometric Function in order to find the measure of "x":

`tan\alpha=(opposite)/(adjacent)`

In this case, you can identify that:

`\begin{gathered} \alpha=21° \\ opposite=x \\ adjacent=18 \end{gathered}`

Then, by substituting values and solving for "x", you get:

`\begin{gathered} tan(21\text{\degree})=(x)/(18) \\ \\ 18\cdot tan(21\text{\degree})=x \end{gathered}`
`x\approx6.9`

Hence, the answer is:

`x\approx6.9`
